What were Jesus and early Christians like?

[Mudhammam]

I'm still uncertain if the claims of Paul, Mark's Gospel, and other early epistles such as Hebrews, aren't sufficient for establishing that the earliest record of Christian belief contains a historical figure named Jesus, regardless if he lived 10 years or 100 years earlier, or if he in fact represents a conglomeration of actual Jewish teachers who took themselves as Yahweh incarnate when speaking their brand of divine wisdom, or if he is a celestial being or idea composed of older myths and philosophies and accidently misunderstood by first century Christian readers as a historical man, either by intention of the authors or by vulgar misinterpretation of an illiterate audience.

And finally, what actual difference does either possibility make in peeling off the layers of Christian origins?
